I’m a PhD student in Computer Science at Columbia University, advised by Xia Zhou. I’m fortunate to also work with Dan Rubenstein and Changxi Zheng. My research develops media provenance and content authenticity technologies, with a recent focus on audio, image, and video watermarking. Check out my for an overview of the field.
I recently interned at Cloudflare Research
working on media provenance. Previously, my research centered on optical sensing and communication, including an internship at NASA’s Jet Propulsion Laboratory
where I developed a hardware-in-the-loop simulator for vision-based spacecraft navigation systems.
I completed my B.A. and M.S. in Computer Science at the University of Chicago, advised by Heather Zheng at the SAND Lab.
